The red-eyed vireo (Vireo olivaceus) is a small American songbird. It is somewhat warbler-like but not closely related to the New World warblers (Parulidae). Common across its vast range, this species is not considered threatened by the IUCN. Vireo is a Latin word referring to a green migratory bird, perhaps the female golden oriole, possibly the European greenfinch. The specific olivaceus is Neo-Latin for 'olive-green', from Latin oliva ('olive'). Wikipedia →
